G46J straight-through rubber lined diaphragm valve
Product Name:
G46J straight-through rubber lined diaphragm valve
Description:

直通式衬胶隔膜阀 G46J

产品特点:设计与制造:BS5156 结构长度:BS5156 法兰连接尺寸:BS4504、DIN2532、JIS B2212、ANSI B16.1、ISO2004 EG46W无衬里隔膜阀,EG46J直通式衬胶隔膜阀

部件列表:1.阀体 2.阀体衬里 3.隔膜 4.阀瓣 5.阀杆 6.阀盖 7、手轮

二、用途:

直通式衬胶隔膜阀专用于控制非腐蚀性或一般腐蚀性介质,阀体内腔表面无衬里或覆有可供选择的各种橡胶、适用于不同工作温度和液体管路。
适用温度:≤85℃、≤100℃、≤120℃、≤150℃(按照衬里和隔膜材料)
压力等级:PN(MPa) 0.6 1.0 1.6

三、材料:

阀体:铸铁、球墨铸铁、碳钢、不锈钢
阀盖:铸铁、球墨铸铁、碳钢、不锈钢
衬里:无衬里、橡胶
隔膜:橡胶
阀瓣:铸铁、碳钢
阀杆:碳钢、不锈钢
手轮:铸铁

四、测试:

衬里层:电火花检测
试验与检验按BS6755标准
公称压力:PN(MPa)
阀体:PN×1.5
密封:PN×1.1

五、结构特点:

隔膜阀是一种特殊形式的截止阀
1. 弹性密封的开闭件,确保没有内漏;
2. 流线型的流道,使得压力损失小;
3. 没有填料函,因此没有外漏;
4. 阀体与盖被中间隔膜隔开,使得隔膜上方的阀盖,阀杆等零件不受介质侵蚀;
5. 隔膜可更换,维护费用低;
6. 衬里材料的多样性,可适用于各种介质,并具有强度高、耐腐蚀性能好的特点。
